Corwin's Notes
=====
NGC 6904 was described by JH as "A small straggling cluster of stars
10...11m. One of the 9m, whose place is taken." In spite of the
inconsistency in the magnitude of the brightest star, JH's description and
position is exactly correct. Wolfgang and I put the center of the cluster
just southeast of the 9th magnitude star.
Curiously, neither Reinmuth nor RNGC found this object. It is perfectly clear
on the POSS1 and the DSS. It may not be a real cluster, but JH's object
certainly exists on the sky.
Steve's Notes
=====
NGC 6904
17.5" (8/25/95): appears to be a random scattering of brighter stars mainly noticeable because it includes mag 8 SAO 88571. The brighter stars form a rectangle with side of 3'-4' and a string of brighter stars off the NW vertex extends another 4' to the north. There are roughly two dozen stars mag 9.5-13 in the group besides the mag 8 star. Richest around mag 9.5 SAO 88575 at the SE corner of the rectangle. Listed as nonexistent in RNGC.
